O Cálculo

Metros lineares = perímetro do cômodo - largura das portas. Quarto 4×5 com 2 portas de 80 cm: 18 - 1,60 = 16,4 m + 10% = 18 m. Rodapés se vendem em barras de 2,40 m. No Brasil, alturas populares: 7 cm (padrão), 10 cm, 15 cm (sofisticado). Rodapés mais altos dão look mais elegante em pés-direitos de 2,70 m+.

Tipos no Brasil

MDF/MDP: R$8-20/m (o mais popular). Poliestireno (Poliuretano): R$10-25/m (resistente à umidade). Porcelanato: R$15-40/m (combinando com o piso). Cerâmica: R$5-15/m. O MDF branco é o mais versátil — pinta em qualquer cor.

⚡ CalcWolf Insight

MDF baseboard is 30-50% cheaper than pine and takes paint beautifully. The downside: it swells when exposed to water (bathroom floors, mopping). For bathrooms and kitchens, use PVC or primed pine baseboard that handles moisture without swelling.
